Arizona Emergency Information Network | Tucson officials have issued an Ozone Action Day as ground-level ozone approaches unhealthy levels, prompting sensitive individuals to limit strenuous outdoor activity during peak afternoon hours.

Community Impact | Late-summer heat and seasonal allergens can worsen indoor air quality as residential air conditioning systems continuously recirculate pollutants that become trapped inside homes.

Slow Boring | For much of human history, homes were heated with open indoor fires that produced heavy smoke and dangerous air pollution, highlighting how relatively recent inventions such as chimneys transformed indoor air quality.

Medical Xpress | A new study suggests that exposure to fine particulate matter may damage oral tissues, increasing gum inflammation and accelerating the bone loss associated with periodontal disease.

Nature | A new study suggests that some tree species commonly planted in cities may unintentionally worsen urban air pollution by releasing compounds that contribute to ground-level ozone formation, particularly as temperatures continue to rise.

Legis1 | A new Congressional Research Service report highlights the growing challenge of monitoring and forecasting wildfire smoke, emphasizing the need for stronger federal coordination as smoke increasingly affects communities far from active fires.

Joint Research Centre – European Union | The European Reference Laboratory for Air Pollution continues to support air quality monitoring across the European Union by developing standardized measurement methods, validating new technologies, and coordinating quality assurance programs among member states.
